"While I understand the importance of communicating allergies, I feel that: 1. Blenders should be cleaned after every use (this is basic knowledge in the food service industry). 2. My nephew wasn’t with us, or I would have mentioned his allergy. 3. This reflects a level of carelessness that needs to be addressed. If parents are grocery shopping and send their kids to get ice cream, and the blenders aren’t washed, what happens if a child has an allergic reaction? Is it then the child’s fault for not mentioning it, or should the staff, who are trained to be mindful of allergies, take responsibility to clarify?"
